Dispersed highland farming villages of the Ayacucho basin whose interaction with the Nazca culture during the Early Intermediate Period generated the ceramic and settlement traditions that gave rise to the Wari state.
Absorbed/transformed as the Wari state emerged from Huarpa-Nazca interaction c. 550-600 AD; the Wari capital (already in canonical, start 600) rose in the same Ayacucho valley.
Standard survey of Andean prehistory; covers the Ayacucho Early Intermediate Period sequence (Huarpa) immediately preceding Wari state formation.
